C. first_axis is the z-coordinate of the axis (center) of the arc.
D. second_axis is the x-coordinate of the axis.
E. axis_end_point is the y-coordinate of the end of the arc.

If rotation is positive, the arc is traversed counterclockwise as
viewed from the positive end of the coordinate axis perpendicular to
the currently selected plane. If rotation is negative, the arc is
traversed clockwise. If rotation is 0, first_end and second_end must
be the same as the corresponding coordinates of the current point and
no arc is made (but there may be translation parallel to the axis
perpendicular to the selected plane and motion along the rotational axes).
If rotation is 1, more than 0 but not more than 360 degrees of arc
should be made. In general, if rotation is n, the amount of rotation
in the arc should be more than ([n-1] x 360) but not more than (n x
360).

The radius of the helix is determined by the distance from the current
location to the axis of helix or by the distance from the end location
to the axis of the helix. It is recommended that the executing system
verify that the two radii are the same (within some tolerance) at the
beginning of executing this function.

While the XYZ motion is going on, move the rotational axes so that
they have always covered the same proportion of their total motion as
a point moving along the arc has of its total motion.

slot (intended to correspond to a slot number in a tool carousel).
This command results in the tool currently in the spindle (if any)
being returned to its slot, and the tool from the slot designated by
slot_number (if any) being inserted in the spindle.

If there is no tool in the slot designated by the slot argument, there
will be no tool in the spindle after this command is executed and no
error condition will result in the controller. Similarly, if there is
no tool in the spindle when this command is given, no tool will be
returned to the carousel and no error condition will result in the
controller, whether or not a tool was previously selected in the
program.

It is expected that when the machine tool controller is initialized,
the designated slot for a tool already in the spindle will be
established. This may be done in any manner deemed fit, including
(for, example) recording that information in a persistent, crash-proof
location so it is always available from the last time the machine was
run, or having the operator enter it. It is expected that the machine
tool controller will remember that information as long as it is
not re-initialized; in particular, it will be remembered between
programs.

For the purposes of this command, the tool includes the tool holder.

For machines which can carry out a select_tool command separately from
a change_tool command, the select_tool command must have been given
before the change_tool command, and the value of slot must be the slot
number of the selected tool. */
